Is there an easy way to port this code to gcc4. It uses old obsolete STL templates which do not longer exist in the new version:

 template<typename _Tp, bool __threads, int __inst>
    struct _Alloc_traits<_Tp, MyAlloc_template<__threads, __inst> >
      static const bool _S_instanceless = true;
      typedef __simple_alloc<_Tp, MyAlloc_template<__threads, __inst> >
      typedef __allocator<_Tp, MyAlloc_template<__threads, __inst> > allocator_type;

_Alloc_traits, __simple_alloc and __allocator do no longer exist.

It would be great If anyone could help

Thanx in advance

If you port code written with STL you may *NOT* port the STL headers, *BUT* only your code which uses the STL classes and functions. You have to use the STL which fits to the compiler (not porting the STL). If doing so, there should be only a few parts which don't compile, e. g. code using iterators where major changes may have occured. You can post these errors and we should be able to help you for each of these issues.

Sorry, if my first post was misleading but this code above is not from the STL but uses STL templates from gcc3.3 which are no longer in gcc4. This code is not from STL classes but from the program I am trying to port. I not meant to port the STL, only want to make this piece of code from gcc3 work in gcc4 where Alloc_traits are no longer available.
